  • Patent number: 11845073
    Abstract: Provided are a continuous crystal transformation and ion exchange device and process, belonging to the technical field of molecular sieve manufacturing. The continuous crystal transformation and ion exchange device comprises M+N reaction tanks which are in serial connection, wherein a feed opening of a latter reaction tank communicates with a discharge opening of a former reaction tank by means of a reaction solution circulation pipeline, and a discharge opening of an M+Nth reaction tank communicates with a feed opening of a first reaction tank by means of a reaction solution circulation pipeline. No more than M reaction tanks are used for a crystal transformation process, and no more than N reaction tanks are used for an ion exchange process. The method is used for preparing a finished zeolite molecular sieve product, and has the advantages of high exchange capacity, simple process, low cost and the like.
